Abstract: A wall support mechanism for vertically supporting a wall member such as an acoustical screen, room partition, or the like, on a non-horizontal floor substantially perpendicular to a reference horizontal plane or parallel to a vertical gravity plumb line. The support mechanism further adjusts the height of the wall member. The support mechanism comprises an elongated foot member and a conduit coupled to the wall member and having an inclined end per se or a tilted nut secured to the conduit end with the lower surfaces of the conduit end or nut lying in a plane inclined to the axis of the conduit. The inclined end of the conduit or nut rests on the center portion of the foot member and vertically orients the conduit and wall member relative to the reference plane upon manual rotatable movement of the conduit and nut relative to the foot member. The conduit is releasably secured to the foot member by a lock-nut and bolt arrangement.
